[Alpine-info] Conversion to mix format

[Ken Mankoff]

Hi List,

I'm an Alpine user but I hope it is OK to post a question here.

I'm getting a system-wide slowdown when saving to certain folders. 
I've spent the morning reading up on the alpine-info list and a few 
threads mention this could be related to having large folders in the 
historical formats. In my case I have a few mailboxes with between 
5k and 10k messages and size on order of 200 or 300 MB.

It seems like mix format is the solution, but I'm not clear how to 
convert. How do I find the current format of my mailbox files? 
They've been around for around a decade and created by pine so I 
think they are mbox. I've downloaded and compiled alpine but it does 
not appear to come with "mixcvt". I'm on OS X using fink and I found 
uw-mailutils which includes the uw-mailutil among others. Can this 
be used?

Any advice on a command to convert my existing folder of mailboxes 
to a new format, assuming that will improve access speed, will be 
appreciated.

Thanks,

    -k.
